Join us as we track migration this fall as hummingbirds travel to their wintering grounds. Citizen scientists across North America are observing seasonal changes and reporting hummingbird sightings. Discover how hummingbirds respond to seasonal change.
Fueled by the nectar, hummingbirds double their weight as they prepare to fly hundreds
or even thousands of miles. Males leave first, as early as mid-July. Females follow, and then the young who migrate for the first time all alone.
